| Dynamic data exchange (DDE) is an older technology that is not secure. If possible, use a more secure alternative to DDE, such as object linking and embedding (OLE). |
If you interrupt a macro that opens a DDE channel, you may inadvertently leave a channel open. Open channels are not closed automatically when a macro ends, and each open channel uses system resources. For this reason, it is a good idea to use this method when you are debugging a macro that opens one or more DDE channels.
Example
This example opens the Microsoft Office Excel workbook Book1.xls, inserts text into cell R2C3, saves the workbook, and then terminates all DDE channels.
Dim lngChannel As Long
lngChannel = DDEInitiate(App:="Excel", Topic:="System")
DDEExecute Channel:=lngChannel, Command:="[OPEN(" & Chr(34) & _
"C:\Documents\Book1.xls" & Chr(34) & ")]"
DDETerminate Channel:=lngChannel
lngChannel = DDEInitiate(App:="Excel", Topic:="Book1.xls")
DDEPoke Channel:=lngChannel, Item:="R2C3", Data:="Hello World"
DDEExecute Channel:=lngChannel, Command:="[Save]"
DDETerminateAll
